High frequency induction hardening

Biagini Industries srl (in wich it evolved Biagini Tempra Metalli srl) has always invested in the latest technologies and systems to better meet the demands of customers who intend to temper their products through the method of induction hardening. We have no less than 5 installations for high frequency induction hardening.

Current equipment includes 17 systems with high, medium and low frequency induction hardening and power ranging from 100 kW to 1000 kW. The frequency range allows us to achieve a hardening depth from 0.5 mm to 30 mm. Power on the other hand gives us the possibility to range from small to large size details.

How does high frequency induction hardening differ from medium and low frequency hardening?

High frequency induction hardening is a type of surface heating used for hardening depths from 0.6 to 2 mm. Medium frequency induction hardening is used for hardening depths from 2 to 6 mm and low frequency induction hardening is used for heating which can reach depths up to and exceeding 30 mm.

The working frequency, and the power of a system for induction hardening must be selected according to the requirement for the hardening depth to be obtained, and the size of the detail to be treated.

The large range of systems available always allows us to work with the right frequency/power ratio.
